Total off season. I would say this is a summer program. I would not do this at all if they were playing VB.
They train like 3-5days a week depending on their development level during the pre-season and during the competitive season. VB training starts in November and runs until the beginning of June.
So i am thinking:
Aug(4 weeks)
Sept(4 weeks)
Oct(4 weeks)
But More than likely it will be 8 weeks.
